name: fbn
synopsis: find files by name
usage: fbn PATTERN1 PATTERN2 ...

Find file names that match PATTERNs in current directory and
subdirectories.  PATTERN may contain ? and * as wildcards. Do not
forget to quote to prevent shell expansion of wildcards.

options:
	-c,--containing         Find all names containing all patterns,
	                          On by default
        -e,--exact              Find names that match any of PATTERNs exactly  
        -h,--help               print this help

examples:

	fbn exp                 Find all files containing "exp" in their name, 
                                  equivalent with `fbn -c foo'
	fbn foo                 Find all files whose name starts with "foo"
	fbn bla blub		Find files named either "bla" or "blub"

for more elaborate searches, use the command find(1).
